Abstract
Unusual surface impurity levels of PREPed Ti-51at%Al powders were analyzed using Auger spectroscopy and they were compared with these obtained from bulk starting electrode. Oxygen and carbon contents were varied very much with particle size. Powder surfaces were believed to be mainly covered by a complex compound containing Ti, Al, O, and C. The decrease in contents of oxygen and carbon of powders were attributed to the certain refining reaction of transfer type DC Ar plasma during the powder production.
플라즈마 회전전극법으로 제조된 Ti-51at%Al 금속간화합물 분말에 함유된 불순물의 함량변화를 분석하였다. 산소와 탄소의 함량은 각각 600 및 200ppm 정도로 분말입도에 따라 변하였으며, 이는 주로 원재료에 포함된 불순물의 영향이었다. AES 분석에 의하면 분말표면 산화물은 주로 Ti 및 Al과 산소 및 탄소의 복합화합물로 구성되었으며, 그 두께는 약 100 및
